MediaWiki 1.18 was deployed to all Wikimedia wikis in October. Major features of the new version include:

Support for gender-specific user pages: In languages that have different words for "User" depending on whether the user is male or female, user pages are denoted by the male or the female version, if the user has specified their gender in their preferences.

Better directionality support: MediaWiki 1.18 makes it easier for left-to-right and right-to-left text to coexist on the same page. (Languages affected by this include Hebrew, Arabic, and Persian.)

October also saw the rollout of native HTTPS support to all wikis, so that URLs like https://en.wikipedia.org/ work to access the secure version of our sites.

To improve retention of new Wikipedians, Steven Walling and Maryana Pinchuk from the Community Department collaborated with community members on the English and Portuguese Wikipedia in testing variations in the wording of warning messages. These ready-made messages are used in automated editing tools to alert new users about problems with their edits. A/B testing is used to find out whether more personal, less directives-oriented messages, or a friendlier wording, have an effect on the user's subsequent actions: How often they edit afterwards, whether their subsequent edits are vandalism, whether they contact the more experienced user who issued the warning, and whether that contact is constructive or not.

The tests involved the anti-vandalism tools Huggle and Twinkle, and SDPatrolBot, a bot which warns users when they remove a speedy deletion tag from an article they are working on. Steven and Maryana also started to collaborate with community members to test improvements in the archiving of shared IP talk pages, where many such warning messages to anonymous editors are being left.

Revenue was ahead of plan due to Stanton grant of $ 2.8 million and additional donations ahead of plan of $ 427,751.

Expenses were below plan at $ 5.4 million actual vs. $ 6.7 million plan. Expenses were below plan due to lower than plan expenditures in capital expenditures, chapter grants, recruitment cost and other activities due to being only three months into the fiscal year.

Cash of $ 16 million, which is six months of cash reserves at current spending levels.

"Wiki Loves Monuments" highly successful: Numerous European countries announced their finalists in the "Wiki Loves Monuments" (WLM) contest. During September, participants had been invited to upload photos of their country's cultural heritage to Wikimedia Commons. The event was mostly organized by Wikimedia chapters in the 18 participating countries, and supported by the Foundation's technical work on special features for the upload wizard. The number of new users on Commons more than doubled during September, and almost 170000 files have been uploaded in the contest. The Europe-wide winner is going to be announced in December.

German chapter launches "Wikidata" project: Wikimedia Germany has begun hiring for "Wikidata", an ambitious project to develop a central data repository for Wikimedia projects, similar to the role of Wikimedia Commons as a central repository for multimedia files. The first two phases will address Interwiki links, and infoboxes.

GLAM collaborations on the rise in Israel: A member of Wikimedia Israel reported that the country has joined the numerous Wikimedia collaborations worldwide with institutions from the cultural sector (GLAMs - galleries, libraries, archives and museums). A cooperation has started with the country's national museum, and there are plans for a Wikipedian-in-Residence at The National Library of Israel.
